Not sure if you’ve ever been near a dairy farm before, or like I used to live near a sugar beat factory, plus pesticides, or lung destroying dust season during harvests. Have you seen what agricultural runoff can do to a river?
We’re all dealing with pollution fam it isn’t exclusive to cities. On a broader note urban and rural areas both have various issues so for a lot of people it is just down to which ones you’re willing to put up with. I’ve lived mostly in small farming towns but I’m in a city now and it suits me much better. I’d rather work to improve what I’ve got here than go back.
